SPRING STRUCTURE.

Application iled March, 14, 1925. Serial No. 15,603.

Objects pertaining `to details and econo-- mies of my invention will definitely appear from the-detailed description to follow.

I accomplish the objects of my invention by the devices and means4 described in the following specification. The invention is clearly defined and pointed out in the claims.

A structure embodying the featureslof my invention is clearly illustrated in the accompanying drawing forming a part of this application, in which:

Fig.'I is a fragmentary vertical section of al structure embodying t-he features of my invention.

Fig. II is an enlarged fragmentary vertical section illustrating structural details.'

Fig. III is a fragmentary perspective view of a slightly modified form of base or border frame. 5

In the drawing similar reference numerals indicate similar parts in all of the views. i

Referring tothe drawing, 1 represents the body springs, the structure illustrated being what is known as a double deck structure. The springs are illustrated conventionally.

The springs a're supported by a base comprising a border frame designated by the numeral '2 which is of sheet metal folded or conformed to provide a downwardly facing channel 3 in which the tacking strip 4 of wood, liber or other material is arranged and an inwardly facing channel 5 which is clamped upon the bottom coil 6 of the border springs. The channel 5 is formed by e foldingthe web portion 7 vof thestrip upon itself.

The t'acking st-rip is retained by the at inturned front flange 8' and the curved rear lor inner flange 9, this flange 9` being of such provide a supporting bead for lie at the outside ofthe bead flange 9 and Y are protected thereby, this bead flange 9 a-lso serving tosupport the frame so that the upholstery does not contact therewith', thus preventino wear of the upholstery.

In the modification shown in Fig. III the inner flange 13 is flat to 'correspond with the outer ange M8. This structure does .not have the advantage of the protection 'of the upholstery butfis satisfactory for some uses. The structure' of Fig. II is,however, the preferred-construction in-that the upholstery is protected and the frame is somewhat stronger. I

My improved spring structure is very strong and rigid and at the same timev is compact. This is` particularly desirable owing to the present aim or tendency of doing `away with seat fra-mes in automobiles and to provide very low bodies.

I have illustrated my improvements in a .simple embodiment. I have not attempted to illustrate or describe certain embodiments or adaptations which I contemplate as I believe the disclosure made will enable those skilled in the art to embody or adapt my improvements as may be desired. v T

Having thus described my invention what I claim as new and desire to secure by Let,- ters Patent is:

1. The combination in a structure of the class described with a plurality of body springs, of a supporting base therefor comnox r1s1ng a border frame of sheet metal conormed to provide a downwardly facing channel having an inturned flat flange at its class describedy with a plurality-of. -bodyjj4 springs, of a Sppoifting` base therefor comprising a border frame of sheet metal folded to plyoyidef `anydownwardly facing ybottom channell and; an inwardly cing J'opV chan-V nel, said top channel being clamped upon the said springs, a tacking strip arranged within Said -bottom channel and retained therein by inturned fianges at theedgesof the bottom/Channel, the inner flange being my hand.

conformed to proyid'e f'siuppo'rtorLthel.

frame projecting below the plane of the outer "innige, and gan knfjholstery jir'coyering comprising a sk-irt- A'por'tio'n i" wrapped:I pon said frame and secured to said taeking strip,
